Novels.............They give us better opportunities to visualize.........And, of course, more things can be covered in a less amount of space, in comparison with manga's and novles are more detailed...........And, I grew up reading a lot of novels, and I've only read two manga's(Naruto and Shingeki no kyojin(Attack on titan))............So, I guess I prefer novels..........

" Justice is subject to dispute; might is easily recognized and is not disputed. So we cannot give might to justice, because might has gainsaid justice, and has declared that it is she herself who is just. And thus, being unable to make what is just strong, we have made what is strong just."
